Denny, when I rebuilt the springs on my '37 1/2 ton, I ground off the sharp corners and the worn edges that had been cut into them. It wasn't much, but enough to let them slide and move around. I also smoothed all the flat sides to eliminate any binding. I then greased them all with Moly grease and assembled them. After a year or so and a few thousand miles, I started to play around with the teflon liner. I pulled the front springs off and replaced them with new,I was afraid of the grinding I did, and thought new ones might work better. I greased the new ones and drove another year like that, then gave up and installed the teflon liner. What I found when I pulled them apart was rust where they contact each other and grease everywhere else.
The Poly-liner solved all my problems, It really smoothed out the ride, plus it real quiet now.
I wouldn't worry about the overly bouncy ride the shop manual takes about. The grease won't last that long and the modern shocks will take care of the rest. Some of cars used burlap wraped around the springs and a steel case over that with grease fittings in them. I think the whole stack was cover in grease.
Let the tires down to about 40psi and see how she rides. Then talk with a spring shop about adding teflon buttons to each leaf, you will be glad you did.
My truck is very smooth and quiet on a smooth road, being a short wheelbase, it bounces like a Jeep does (front to back, bronco horse). With a loaded trailer to hold the back down, its much better. Joe
